(Frequently Asked Questions)

Q. Will your class work on a PC, Mac, iPad, iPhone or Android tablet?
A. Yes, our class was recently converted from Flash to HTML 5 and has tested well on PC (Windows), Mac, desktop, laptop, and mobile devices (iOS and Android) with current web browsers. You will need access to a printer for some of our handouts.

Who is the original idex prep?
A.   We are. We were the first. See our blog post

Q. Is the IDEX exam changing for the 2019 code?
A. Yes but the exam has not been updated yet. The new codes became effective January 1, 2020 and CCIDC is in the process of updating the IDEX exam. Their plan is to have the new exam ready by October 2021, however, due to Covid-19, the process has slowed down considerably. PLEASE CHECK FIRST directly with CCIDC for their projected roll out date of their new exam.

Q. Did the IDEX change for the 2013 code and are your materials current with 2016?

A. Yes and yes. The IDEX exam changed on May, 2015 for the 2013 California Building Code (CBC). The IDEX will not be reviewed again (for possible changes) until 2019 for the next code cycle in 2020. Even though the current code is now the 2016 version (adopted by the state into law as of January 1, 2017), the IDEX exam and all of our prep materials changed for the 2013 code, AND, there have not been any significant changes to the current code that affects interior designers or the IDEX exam. Have more questions? Contact CCIDC.

Q. What are your requirements for taking your class? 
You need high-speed Internet access, a computer or mobile device with a Web browser, a printer, the ability to download and read Adobe .pdf files. Students should already have an interior design education and would benefit from having work experience in the interior design industry. Our classes are intended to prepare you to pass the IDEX exam. They are not intended to be complete building codes or interior design classes.

Q. Do I need to install a plug-in or extra software to take your classes?
A. No, but we recommend you first enroll in our one-day FREE demo class.   

Q. Do I really need 75 days to complete your class?
A. No, not at all ...  but we are giving you a lot extra time in case you need it. Our class used to be offered for 60 days but some designers always asked for time extentions. Since everyone reads at a different pace, has different levels of education and work experience, plus a busy schedule, we are giving you the best prep course with a long access time to help you. It is up to you, the student, to look through the materials and pace yourself according to your situation and lifestyle, so you can finish your class within the required timeframe.

Q. What do past students say about your class?
A. They love it! Here’s some testimonials.

Q. Why have you discontinued the  “IDEX Prep eGuide”?
A. Since we are now offering the highest quality IDEX Prep class in an easy-to-use framework, we have discontinued the eGuide which we first published in 2009.

Q. I don’t live in California. Can I take your prep class to help me become a Certified Interior Designer?
A. Yes, you can take our IDEX Prep class from anywhere. If you want to take the IDEX EXAM however, you must first apply for certification with CCIDC and meet their education, experience and requirements.

Q. Are CEUs available if I take your class?
A. Yes, but only for existing CIDs, and not IDEX candidates. Our class is accepted by CCIDC for 1.0 unit of CEU credit for existing CIDs only. Note: 1.0 unit = equals 10 hours of class time.

Q.What is your refund policy?
A.Please review our Terms & Policies page.
